8-bit tinyAVR MCUs feature up to 8KB Flash

Article By : Microchip Technology

The devices feature 20MHz internal oscillator and high-speed serial communication with USART operating voltages ranging from 1.8V to 5.5V.

Microchip Technology has rolled out a new line of 8-bit tinyAVR MCUs featuring core independent peripherals (CIPs). The four devices range from 14 to 24 pins and 4KB to 8KB of Flash memory and will be supported by Atmel START, an online tool for intuitive, graphical configuration of embedded software projects.

The new ATtiny817/816/814/417 devices provide features to help drive product innovation, including small, low pin count and feature-rich packaging. Other integrated features include a CIP called Peripheral Touch Controller (PTC), an event system for peripheral co-operation, custom programmable logic blocks and self-programming for firmware upgrades as well as non-volatile data storage.

CIPs allow the peripherals to operate independently of the core, including serial communication and analog peripherals. Together with the Event System, which allows peripherals to communicate without using the CPU, applications can be optimised at a system level. This lowers power consumption and increases throughput and system reliability.

The MCUs also feature 20MHz internal oscillator, high-speed serial communication with USART operating voltages ranging from 1.8V to 5.5V, 10-bit ADC with internal voltage references and sleep currents at less than 100nA in power down mode with SRAM retention.

Accompanying the release of the four new devices, Microchip is adding support for the new AVR family in Atmel START, the online tool to configure software components and tailor embedded applications. This tool is free of charge and offers an optimised framework that allows the user to focus on adding differentiating features to their application.

The 8-bit tinyAVR MCUs is available in mass production today in QFN and SOIC packaging. Devices are available in 4KB and 8KB Flash variants, with volume pricing starting at $0.43 for 10K units.
